Preparation of benzoic acid lab report. By going through the process of synthesizing benzoic acid I was able to obtain the necessary data needed for determining my % yield of benzoic acid and creating a recrystallized product that I would eventually need for a later experiment. 1) Write an equation which describes the reaction which has occurred. Lab Report for “Synthesis of Benzoic Acid” Complete questions 1-6 in the experimental section of this laboratory procedure. 89% error. ORGANIC SYNTHESIS: BENZOIC ACID VIA A GRIGNARD REACTION EXPERIMENTAL PROCEDURE Work in pairs but hand in separate, individual reports. 6%, a high value for the purity showing that the recrystallization was very effective in removing impurities. After that, by using the Buchner funnel, filter paper and Buchner flask, the product (benzoic acid) was filtered. Write an equation which describes the reaction which has occurred. Preview text Kennedy Smith* Lilia Barnett CHEM 238- 10 October 2022 Synthesis of a Benzoic Acid Derivative Introduction Discovered by Victor Grignard, grignard reagents are strong nucleophiles that are able to react with a vast number of electrophiles, such as carbon dioxide. This laboratory report investigates the chemistry of carbonyl compounds under basic conditions, focusing on aldol condensation and haloform reactions. 7 billion by 2027, reflecting a compound annual growth rate of 3. Each lab group will be provided with a one gram sample of crude benzoic acid. Covers recrystallization, redox reactions, titration, and gas laws for undergraduate chemistry education. Conclusion: When doing this experiment I made a batch of crude benzoic acid, this batch was meant to be used for a titration, recrystallization, six melting points and a TLC experiment. 2 grams of sodium benzoate were dissolved in water and reacted with hydrochloric acid to form benzoic acid. College-level organic chemistry. In today’s experiment, the phenylmagnesium bromide will be reacted with CO2 to form a benzoate salt, which is then hydrolyzed to form benzoic acid. Nov 5, 2024 · The hypothesis for the synthesis of benzoic acid states that using hot water as a solvent for the recrystallization of benzoic acid, would show a higher success measure, which would be evident by the melting point range and percent yield calculation. What would the Grignard Reagent be converted into if water accidentally got into the flask? Nov 3, 2025 · The process of benzoic acid synthesis is remarkably colorful. Mar 30, 2023 · the precipitation of the benzoic acid was completed using the dropper. It was observed through the melting point percent error calculations that the impure/crude resulted in a somewhat low of 3. Your group will be responsible for planning and implementing a procedure for the purification of the crude benzoic acid. Sep 28, 2017 · The document summarizes an experiment to synthesize benzoic acid from sodium benzoate. University of the Philippines lab manual for General Chemistry I, featuring 12 experiments, safety guidelines, and scientific procedures. Nov 5, 2024 · Figure 2 and 3 displays the findings for the synthesis of benzoic acid during and after crystallization by recrystallization of impure benzoic acid. . Key procedures, observations, and results are documented, including the synthesis of benzalacetophenone and benzoic acid, alongside analytical techniques like TLC and melting point measurements. Lab report on benzoic acid synthesis: reaction, yield, IR, NMR, mass spec analysis. This benzoic acid sample will be 85-90% pure, and will be contaminated with both 14-dimethoxybenzene and red dye #40. 2) What would the Grignard Reagent be converted into if water accidentally got into the flask? The benzoic acid purity came out at 93. It starts with the potassium permanganate, a dark purple color in its solid and aqueous solution form. Feb 25, 2026 · A recent industry report suggests that the global benzoic acid market is projected to reach over $1.
